SPECIFICATION forming part of Letters Patent No. 547,512, dated October 8, 1895.
Application iiled March 9, 1835. Serial No. 541,177. (No model.)
My invention relates to improvements in valves for inflatingthe pneumatic tires of bicycle and other wheels, and its object is to .provide a device of this character which shall possess important advantages with respect to efficiency in operation.
The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.
In the accompanying drawings, Figure l isv au elevation showing a portion of a bicyclewheel with my improved valve applied thereto. Fig. 2 is an elevation of the valve detached, on an enlarged scale. Fig. 3 is alongitudinal sectional view. Fig. t is a view, partly in section -and partly in elevation, showing'the parts comprising the same disconnected or detached from eachother. Fig. 5 is a cross-section on the lineas fr, Fig. 3. Fig. 6 is sectional View showing a modiiicationin the manner of connecting the valve with the tire.
In the said drawings the reference numeral 1 designates the pneumatic tire secured to the semicircular rim of the wheel in any ordinary or suitable manner.
The numeral 2 designates the shank of the valve, consisting of a tapering cylindrical metal tube having a number of peripheral projections or ribs 3, which engage with the nipple 4 on the tire, and by which the shank is held in place. rlhis tube is provided at its inner end with a cylindrical bore 5, which communicates with an enlarged cylindrical recess 6, formed with a number of longitudinal grooves 7, which form air passages. At its outer end the tube is formed with a cylindrical recess 8, forming an annular chamber to receive a cup-shaped head. Located in this tube is a stem 10, comprising the cylindrical portion 13 and cylindrical head 14,
which latter is cup-shaped or formed with an annular recess to receive a washer l5, which constitutes a valve. A coiled spring 16 surrounds the rod l0, the tendency of which is to force the rod and its head and valve out- Ward.
The numeral 17 designates a cap, screwthreaded interiorly to engage with corresponding heads on the exterior of the shank. This cap is provided with an annular flange 18, which forrnsa seat for the valve l5, and is also formedpwith an opening 18a and a screwthreaded recess to receive a screw-plug 19.
The numerals 2O and 2l designate washers for making air-tight joints.
The manner of using the device is as follows: The screw-plug is removed and the cap is connected withan air-pump. Air is then forced through the opening in the cap, forcing the valve away from its seat and escaping through the grooves in the shank into the tire. When the pressure in the valve is relieved, the back-pressure, aided by the coiled spring, will force the valve against its seat, preventing the escape of the air therefrom.
In the modification shown in Fig. 6 the peripheral ribs or projections on the shank are dispensed with and the inner end ofthe shank formed witha flange, which is connected with the tire by a nut and washer.
A valve constructed as above described lwill be very efficient in operation,as it works automatically and effectually prevents the escape of air, and it possesses advantages which will be apparent to those skilled in the art to which the invention pertains.
Having thus fully described my invention, what I claim is 1. In an inflation valve, the combinatio with the shank having a cylindricalopening at its inner end, an enlarged recess formed with aV groove or grooves, and the cylindrical recess at the outer end, the valve comprising the cup shaped head seated in said recess, the washer, and the stem secured to said'head and pointing toward the outlet of the-shank, of the screw cap engaging with said shank, provided with an annular valve seat and the washer surrounding said valve seat, substantially as described.
2. In an inflation valve, the combination IOO with the shank having a cylindrical opening seat, and the screw plug in the outer end of Io at its inner end, an enlarged recess formed the cap, substantially as described. with a groove or grooves and aeylindrical re- In testimony whereof I affix my signature cess at the outer end, the stem located in said in presence of two Witnesses.
5 recess and pointing toward the tire, the cup shaped head, the valve located therein, and GEORGE W. BENNUM. the coiled spring, of the screw cap engaging Witnesses: with said shank, provided With an annular HENRY O. BENNUM,
valve seat, the washer surrounding said valve GEORGE M. SPAULDING.
